Will Scotchshield (Ultra) film keep my glass from breaking?

This is difficult to answer with any degree of certainty because it is difficult to test for this. Window glass varies in strength from piece to piece, and lot to lot. So, if a Scotchshield protected window were impacted, yet, failed to break, it would be difficult to determine if the glass alone, the film alone, or the film and glass together resisted the breakage. When glass breaks, Scotchshield Ultra Film demonstrates it’s best performance!
